TDS-NJ-4W-10W-20W Hydroxypropyl Methyl Cellulose(HPMC)
Hydroxypropyl methylcellulose ether is a water-soluble white to light yellow powder, which is divided into 4w viscosity, 10w viscosity and 20w viscosity according to different viscosity, and has the following characteristics:
It can provide thickening, adhesion, water retention, suspension stability, emulsification and film formation properties required by mortar products;
The molecular structure is specially designed for mortar products, with the characteristics of small particle size and fast dissolution speed, which can improve the construction performance of mortar, such as opening time, anti-slip resistance and bonding force;
Products with different viscosity and gel temperature can be provided according to customer needs, with a wide range of applications; modified cellulose ether can avoid easy clustering in low temperature water and dissolve quickly in cold water
scope of application
This product is widely used in all kinds of fluid mortar and cement concrete, especially for surface layer cement-based self-leveling mortar and gypsum self-leveling mortar water retention thickening and suspension modification.
